The African continent faces a growing battle for achieving adequate and safe access to power and potable water. Without addressing the need for power and water, Africa will not achieve its true growth potential as the “world’s last growth frontier”. Macro-economic forces such as climate change, growing populations, increasing urbanisation rates and deteriorating existing water infrastructure, are all encouraging local governments to shift towards Non-revenue water (NRW) reduction strategies. In collaboration, Frost & Sullivan and SIWI, conducted an “Analysis of the Investment Opportunities for Non-Revenue Water in South Africa and Mozambique”, with a more detailed assessment of two select municipalities per country. Using historic (2010) up to present day (2016) figures, a thorough understanding of the nature and size of the NRW problem, the size of the opportunity (both private and public sector), and the relative governance bottlenecks were identified.
